IMPROVEMENT IN SNAPI-HOOKS.

The Schedule referred to in these Letters Patent and making part: of the same.

To all whom it may concern: A

Be it known that, L'RALPH L. FRASER, of Westernville, in the county of Oneida, and State of New York, have invented a new and improved Safety- Hook or Attachment for.V Round Driving-Rents or Straps; and l do hereby vdeclare that the following isa t'ull and exact descriptimi thereof, ret'er'ence being badlto the accompanying drawings, in which- ,v Flgure lis a side view ot' the hook closed, a portion being represented in section to shown .the spring i and slot- Figure 2 is a front view ot' the hook, shown open. Figure 3 is a back view ofthe salue closed. Like letters indicate corresponding parts in the different figures. A My improved hook is designed especially for round driving-reins, as a means of attaelnuent to the ring nt' the bit, and t'or other similar uses where a rein or line of round form is used; and

I t consists essentially of a shank of cylindrical form,

j and preferably tubular, to receive the rein, and a hook ot' suitable forni and size, and a revolving'slceve, fitting over said cylinder, having an arm or point, which iscoiucidentl with the end ofthe hook atone position, and a spring arranged to maintain it in that position, except when forcibly removed.

ln the drawings--` A is the hook;

lt, the cylindiical shank; and

C, the revolving sleeve, with arm c; while l 'i indicates the spring, bearing against the outer end of the sleeve, at a point dia'xnctrcally opposite. to the arm c, where it is slightly notched or recessed, leaving aniucline at either side there-ot'. As the spring re ts in this notch or recess when the hook is closed, its pressure retains it in that position; but when it 1s re quired to open the hook, alittle force applied causes the sleeve to rotate, bythe yielding of the spring against the int-lines.. l l A The rciu is iuscrted within the hollow cylndn'cal portion B, and secured by riveting through. I pret'er to enclose this sleeve-portion ot' the hook in a tial-tile,A E, which serves as a protection to the spring, and also to graduate the contour from the larger diameter to the shank. This t'errule maybe'corrugated, as shown, 0r otherwise ornanieuted, and plated or gilt ou the better class ot' harness.

The cylinder C is also preferably corrugated or flutcd longitudinally of its direct-ion, which enables it to be moreeasly turned by the hand, as well as improves its appearance. y v t The spring L may be ofthe shape represented, or of any other form that. will lnaintain suiiicieut pressure to hold the sleeve in the position required to'keep the hook closed.

.lhe formot' this hook is very neat for use upon round reins, while it isvstrong, durable, and entirely safe from becoming disconnected while in use.

What I claim as my invention, and desire to secure by Letters Patent, isy The rota-ting sleeve C, ibrrned with arm c, and` encircling the cylindrical shank B, in combination withv said shankand the hook A, 'cast therewith, and the retaining-spring t", when the parts are. constructed and adapted to operate together, substantially as described.

In witness whereof, I have hereunto signed my mame, in the presence of two subscribing witnesses.

RALPH L. FRASER.
